Has anyone tested and then a line appears after the time limit that has colour and gone on to be positive? Tested and didn't appear to be a line, went out for 2 hours, came back and a second line was clearly visible and with colour. Don't know how long after. Just wondering if this has happened to anyone else and been pregnant? At this point we are happy either way and will re test in the am but just thought I'd see if this has happened to others.
